Subject to the US Cloud Act — a US judge can demand our data without our consent. Excluded in production.
Useful tools in offline dev POCs, but no patient data flows through these APIs in production. Production = Mistral EU.
US tracking incompatible with GDPR post-Schrems II. We use Matomo (self-hosted) + Plausible (EU) when needed.
Drug database owned by a marketing group. Conflict of interest. We use Thériaque + ANSM + RxNorm (open / public).
No greenwashing. Every milestone has a target date and a measurable deliverable.

Predictive models (cardio risk, oncology) · MDR class IIb.
Our fine-tuned CamemBERT-bio models are published on HuggingFace. Public good — the French medical community benefits.
Public npm libs for ICD-10 / CCAM / LOINC mapping to FHIR R4 France Core. Shared standard.
Cardio risk, oncology and other predictive models remain proprietary. Competitive moat on which MDMC's durability rests.
How these bricks fit together to form a sovereign, encrypted, portable health passport.
